In Chipping Norton there is an area of tarmac that contains around 5 marked bays. In front of these there is a standard limited waiting sign (e.g. Between 8am and 6pm waiting allowed for 30 mins return prohibited for 30 mins). There is no problem with this.
To the side of this there is a [non-rectangular] small area of tarmac that has a legitimate looking parking sign ('P') with a motorcycle sign below it. This small area of tarmac does not have bay markings on it although it does have marked on the tarmac as 'Parking for motorcycles only' (or similar).
The road by the side of the tarmac has no no parking signs by the side of it and chipping norton is not a controlled parking zone (at least as I am aware).
I have just got a pcn for parking my car on that area of tarmac, code 3 'Parking in a parking place or area not designated for that class of vehicle'. I am confused as to the legality of the pcn as I believed the 'P' [parking] sign with the motorcycle below needed a marked (and legal) bay to which to refer to. As it stands, there is no clearly defined area. The Traffic Signs Manual chapter 3 paragraph 7.6 quotes, 'Bay markings are normally used with the above signs (see table 7-1), although there might be circumstances where such markings are not required, e.g. within a lay-by.' But is not anymore specific in this area.
Anyone got any ideas as to the enforceability of the motorcycles only parking sign?
